Abstract
The asymmetric unit of the title salt, C4H12N22+·2C4H5O6−, comprises one half of the piperazine-1,4-diium dication lying on a twofold rotation axis and one 3-carboxy-2,3-dihydroxypropanoate anion. In the crystal, the ions are linked into a three-dimensional network by N—H...O, C—H...O and O—H...O hydrogen bonds.
